Hi,
I am calling m_reader.PDFGotoPage() and the code executes, but the implemented method OnPageChanged() also gets called () and a random page opens in the end.
I am calling PDFGotoPage() inside onActivityResult()
It's normal that the method OnPageChanged() is called when you call m_reader.PDFGotoPage() as the you are changing the current visible page..
Using the demo project it's working without problems..so try to check if you have modified something that causes this behavior..
